Low-cost Prussian blue analogues for sodium-ion batteries and other metal-ion batteries

Abstract

As a class of promising cathodes in the field of large-scale power storage systems especially for the alkali-metal-ion batteries (MIBs), Prussian blue (PB) and its analogues (PBAs) have received wide...

P-doped spherical hard carbon with high initial coulombic efficiency and enhanced capacity for sodium ion batteries

“…Among the various kinds of cathode materials, Prussian blue (PB) and its analogues (PBAs) have been widely researched due to the three dimensional open framework, high theoretical capacity, and simple synthesis method. 39 According to the XRD result in Fig. S7a, † FeMnHCF shows the monoclinic phase, with the space group P 2 1 / n , which is different from the common face centered cubic structure.…”

The innovative design of high-performance layered transition metal oxides for sodium-ion batteries from a commercial perspective

“…One cathode alternative with the best prospects, layered transition metal oxides (LTMOs), has attracted intense research interest, not just because of their non-toxic nature, high theoretical capacity, easy processability, mature manufacturability, suitable voltage, and abundant resources but also because of their potentially low cost. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] LTMOs have P2, P3, O2, and O3 phase and tunnel structures, all of which have advantages and disadvantages. Single-phase materials have been studied a lot, yet the commercial implementation of LTMOs is still limited by their insufficient rate capability, low energy density, insufficient cycling stability, and air instability.…”

Introducing zinc ions into manganese-based Prussian blue for improving the structural stability of sodium-ion batteries

“…Prussian blue analogs (PBAs) are the most competitive candidates among the cathodes for sodium-ion batteries in large-scale energy storage, 1,2 among which MF-N not only has a high theoretical capacity of 170 mA h g −1 but also has a low fabrication cost and high operating voltage, which possesses great advantages in practical applications. 3–5 However, the electrochemical performances of this material face huge challenges due to lattice channel instability and drastic phase transitions during working processes. 6–8…”
